Thinking of building a couple of cubo 15's to compliment a pair of 2x15" + comp/horn in a small disco type set up.
Problem is, is that my 2 ch Berry x-over only has a HP of 25hz, will the Kappa 15LF be ok in these cabs with this arrangement, driven with 250-300wrms? Or will I exceed xmax? Running up to 70-80hz. Not after huge amounts of power here as you may guess!
Under normal circumstances that isn't a problem at all. Unless "unnormal" events take place it can last a lifetime. Unnormal events are ussually low frequencies that are present in large quantities (sometimes not intended), eating up a lot of power whilst not being heard, encouriging anyone to put it louder. Also highly compressed signals can be a danger, especially in combination with the former events.
Under normal circumstances I won't be a problem, under unnormal circumstances it might.
